Messing up our climate with excessive CO2 emissions is taking huge risks. With the concentration of CO2 in the atmosphere rising faster every year, and massive releases of stronger greenhouse gases like methane (natural gas), it is likely that sea levels will continue to rise worldwide. What people don’t remember is that small changes in sea level have happened all along, and that it wasn’t that long ago when, because we were still emerging from the last ice age, sea levels were several feet (or tens of feet) lower. Now humanity has built so heavily in areas near sea level that almost any rise is reflected in an increased frequency of damaging floods. In some areas the flooding already happens from a high tide, and no storm or other weather event is needed.
There is a lot more ice (and potential sea level rise) than most people realize. Another thing people don’t realize is that there is enough ice on land in just Greenland and Antarctica to increase sea levels by 200 FEET! If some portion of this increase happens quickly, in less than a month, for instance, humanity will be completely surprised and “caught with our pants down” as famine and pandemic result. So much of our food reaches us via container ships that, when the container ports are shut down by a sea level increase of a foot or two, shiploads of food will spoil at sea, grocery store shelves will get sparse, and there is a danger of people panicking and making runs on the grocery stores and banks.
I certainly hope humanity comes to its senses soon. Thanks for reading — Tim
